DESCRIPTION
The GME TH10 is a telephone style intercom unit suitable
for both land based and marine installations where wired
communications is required between two or more locations.
Individually numbered buttons allow selective paging of up
to 10 stations.
INSTALLATION
WIRINg
To prevent loss of performance, the wire used should have
a minimum diameter of 0.5 mm and should be no more
than 500 meters in length. To determine the number of
wires required, use the following formula:
No. of St 3 = number of wires
(e.g. 5 st 3 = 8 wires)
1. Remove the screw in the mouthpiece recess of the case
and lift the case clear.
2. Feed the cables through the hole in the centre of the
case bottom and after removing the insulation from the
end of each wire, connect them to the terminal block
inside the intercom according to Figure 1.
3. To help eliminate wiring errors, connect each intercom in
sequence, then test each installation before proceeding
to the next. This allows you to identify and correct any
wiring errors as you go.
MOUNTINg
The TH10 may be installed on any flat surface using
the mounting bracket supplied. Postion the bracket in
the desired location with the mounting lugs protruding
outwards and upwards, and secure with two 3 mm
diameter screws. Place the TH10 over the four protruding
lugs so that they locate in the slots in the case bottom,
and slide the Intercom downward until it locks. To remove,
use the reverse procedure.
POWER REqUIREMENTS
The TH10 requires a 12 Volt DC power supply. The supply
used will depend on your installation.
MARINE INSTALLATIONS
The TH10 can be connected directly to the 12 Volt battery
on board your boat using a FUSED power lead.
1. Connect the RED lead to the ‘+’ on the terminal block.
2. Connect the BLACK lead to the ‘-’ on the terminal block.
LAND BASED INSTALLATIONS
The TH10 should be connected directly to a 12 Volt DC
power supply capable of at least 100 mA such as the
GME Model BCE1445.
1. Cut the DC plug from the end of the BCE1445’s DC lead.
2. Connect the BLACK/WHITE STRIPE lead to the ‘+’ on the
terminal block.
3. Connect the BLACK lead without the stripe to the ‘-’
on the terminal block.
OPTIONAL ExTERNAL BUzzER
In high noise environments, it may be necessary to install
an external buzzer so that the station being called can
be alerted. Any low current 12 Volt buzzer can be used.
The buzzer should be connected to the terminal block
inside the intercom so that the POSITIVE wire of the
buzzer connects to ‘B’ and the NEGATIVE wire of the
buzzer connects to ‘-’ as shown in Figure 1.
I.D. LABEL
Write or type the station’s call number on the label
supplied, peel off the backing, and apply to the unit
in a visible location.
OPERATION
1. Pick up the handset and momentarily press the button
corresponding to the station you wish to call. The buzzer
will sound at the called station.
2. The person being called can then pick up the handset
and talk in the usual manner.
3. When you have finished, place the handset back onto
the base.
Note:
The system has been designed so that during a
conversation, any handset in the system can be lifted from
its base and used to join in.
